Patent CA-2234966-A1 (CA)
Inventor: BALISTEE BRIAN G
IPC: B26B21/54
Filed: 1998-04-17
Abstract: A blade edge with increased durability and a reduced cut force and a method for manufacturing the same. The blade edge is thickened by depositing a coating or grinding. A thin film having a low coefficient of friction, such as amorphous diamond, is then applied to the edge. An additional layer of a lubricious polymer may then be applied. The resulting blade edge has a significantly reduced cut force over existing razor blades and also has greatly increased durability.

Title: Wet end starch application
Inventor: TAYLOR JOHN A
IPC: D21H23/48
Filed: 1997-02-06
Abstract: A suspension of uncooked starch and water is applied to web forming on the wire (12) of a paper machine. The suspension at a consistency of 2-10 % is applied to the surface of the web as a free falling curtain (30) from the downwardly opening extrusion slot of a coater die (25). The die lips are chilled to produce sweating by moisture condensation to prevent build-up of coating particles on the die lips.

Title: Channel allocation method for a packet network
Inventor: KARI HANNU
IPC: H04J3/16
Filed: 1997-06-03
Abstract: A method for allocating a data transmission channel/sub-channel in a telecommunication network. A network includes a telecommunication controller (BTS) and several terminal equipments (MS). The transmission channel is divided into one or more time slots, each of which comprises one or more sub-channels. One or more time slots or sub-channels can be used as a control channel that is further divided into one or more control sub-channels. The terminal equipments (MS) send data in data packets at least on one sub-channel. The telecommunication controller (BTS) sends to the terminal equipments (MS) information about control sub-channels and their allocation situation. Different priorities (P1 to P4) are assigned to the data packets to be sent and to the control sub-channels. On the basis of the priority of the data packet to be sent and the priority of the control sub-channels, each terminal equipment (MS) determines the moments when it may send a channel request.
Patent CA-2257550-A1 (CA)
Inventor: MANN ARMIN

Filed: 1999-01-13
Abstract: A process for suppressing total echoes comprising a plurality of partial echoes in telecommunications (TK) equipment such as terminals, transmission systems, or switching equipment by means of adaptive FIR (= Finite Impulse Response) filters that simulate the total echo and subtract it from the echo-affected useful signal transmitted to the respective TK equipment, whereby n partial FIR filters are provided, which respectively simulate a partial echo, is characterized in that m parallel, mutually independent TK channels are provided with an echo suppression function and that for this purpose a variable sub-quantity of the partial FIR filters is assigned to a TK channel to be operated, respectively, as required depending on the number of partial echoes and the size of the occurring delay times between signal and echo.      This permits effective echo suppression without significant memory space and computational effort even for a large number of m parallel, mutually independent TK channels, such as must be processed in switching equipment or gateways.

Abstract: Feuils fabriqués en polyéthylènes et en matériaux de charge, et articles fabriqués à partir de ces feuils, présentant une vitesse supérieure de transmission de vapeur d'eau (WVTR) par rapport aux feuils actuels basés sur des polyéthylènes classiques de Zeigler-Natta. On produit ces polyéthylènes dans un processus comportant un catalyseur de métallocène. On peut fabriquer les feuils au moyen d'un procédé de coulage et leur conférer une teneur en charge extrêmement variable, en général, selon des rapports entre polyéthylène et charge de 30/70 à 70/30. Ces polyéthylènes à base de métallocène, quand on les combine à une charge, permettent également l'extrusion de feuils plus minces, ce qui permet d'obtenir des feuils plus légers et plus mous. Les m-polyéthylènes utilisés pour fabriquer ces feuils présentent généralement un indice de largeur de répartition de composition supérieur à 50 %, un M¿w?/M¿n? inférieur à 3 et un M¿z?/M¿w? inférieur à 2.

Title: Faraday rotator
Inventor: KAWAI HIROTAKA
IPC: G02B27/28
Filed: 1999-03-01
Abstract: Disclosed is a Faraday rotator capable of reducing the temperature dependence on a Faraday rotation angle, thereby enhancing the temperature characteristic, particularly, in a service environment in which the magnetization direction is variable, and an optical device using the Faraday rotator. The Faraday rotator includes a Faraday element which rotates the polarization plane of polarized light rays passing through the Faraday element when an external magnetic field is applied to the Faraday element. In this Faraday rotator, assuming that an angle between a magnetization direction of the Faraday element and a light ray direction is taken as .alpha., the amount of the temperature-dependent change in Faraday rotation angle is reduced by applying the external magnetic field in a direction in which a first amount of the change in Faraday rotation angle due to the temperature dependence on the angle .alpha. and a second amount of the change in Faraday rotation angle due to the temperature dependence on the Faraday effect satisfy a relationship in which the sign of the first amount is plus or minus, the sign of the second amount is minus or plus, and the absolute value of one of the first and second amounts is less than twice the absolute value of the other amount, more preferably, substantially equal to the absolute value of the other amount.
